fuzzyfinder
fuzzyfinder is a fuzzy finder implemented in Python. It matches partial string entries from a list of strings, and works similar to the fuzzy finder in SublimeText and Vim’s Ctrl-P plugin.
Some notable features of fuzzyfinder are:
Simple, easy to understand code.
No external dependencies, just the Python standard library.
An in-depth overview of the algorithm behind fuzzyfinder is available in this blog post.
Quick Start
Installation
$ pip install fuzzyfinder
Usage
>>> from fuzzyfinder import fuzzyfinder
>>> suggestions = fuzzyfinder('abc', ['acb', 'defabca', 'abcd', 'aagbec', 'xyz', 'qux'])
>>> list(suggestions)
['abcd', 'defabca', 'aagbec']
>>> # Use a user-defined function to obtain the string against which fuzzy matching is done
>>> collection = ['aa bbb', 'aca xyz', 'qx ala', 'xza az', 'bc aa', 'xy abca']
>>> suggestions = fuzzyfinder('aa', collection, accessor=lambda x: x.split()[1])
>>> list(suggestions)
['bc aa', 'qx ala', 'xy abca']
>>> # With the appropriate accessor you can pass non-string collections, too
>>> collection = [1234, 5678, 7537, 888, 57, 77]
>>> suggestions = fuzzyfinder('57', collection, accessor=str)
>>> list(suggestions)
[57, 5678, 7537]
>>> # Make filtering case-sensitive
>>> collection = ['bAB', 'aaB', 'Aab', 'xyz', 'adb', 'aAb']
>>> suggestions = fuzzyfinder('Ab', collection, ignore_case=False)
>>> list(suggestions)
['aAb', 'Aab']
>>> # By default, elements with matches of same rank are sorted alpha-numerically
>>> suggestions = fuzzyfinder('aa', ['aac', 'aaa', 'aab', 'xyz', 'ada'])
>>> list(suggestions)
['aaa', 'aab', 'aac', 'ada']
>>> # Preserve original order of elements if matches have same rank
>>> suggestions = fuzzyfinder('aa', ['aac', 'aaa', 'aab', 'xyz', 'ada'], sort_results=False)
>>> list(suggestions)
['aac', 'aaa', 'aab', 'ada']
>>> # Highlight matching substrings when printing to the terminal
>>> collection = ['apple', 'banana', 'grape', 'orange', 'pineapple']
>>> suggestions = fuzzyfinder('ape', collection, highlight=True)
>>> list(suggestions)
['gr\x1b[42mape\x1b[0m', '\x1b[42map\x1b[0mpl\x1b[42me\x1b[0m', 'pine\x1b[42map\x1b[0mpl\x1b[42me\x1b[0m']
>>> # Custom highlighting (use with ANSI, HTML, etc.)
>>> parentheses = '(', ')'
>>> suggestions = fuzzyfinder('ape', collection, highlight=parentheses)
>>> list(suggestions)
['gr(ape)', '(ap)pl(e)', 'pine(ap)pl(e)']Similar Projects
